NASA's Jet Propulsion Laboratory will host a briefing at 9 a.m. PST (noon EST) Monday, March 2, to discuss the March 6 arrival of the agency's Dawn spacecraft at the dwarf planet Ceres. The news briefing, held at JPL's von Karman Auditorium at 4800 Oak Grove Dr., Pasadena, California, will be broadcast live on NASA Television and streamed here.

Ceres, located in the main asteroid belt between Mars and Jupiter, is the largest unexplored world of the inner solar system. Dawn will not only be the first spacecraft to reach a dwarf planet, it will be the first spacecraft ever to orbit two different worlds in deep space.

Dawn was the first spacecraft to orbit a body in the main asteroid belt when it explored the giant asteroid Vesta from 2011 to 2012.

NASA's Jet Propulsion Laboratory invites you to watch live and chat about everything from Mars rovers to monitoring asteroids to cool cosmic discoveries. From the lab to the lecture hall, get information directly from scientists and engineers working on NASA's latest missions.
